UNITED STATES PATENT OFFICE.

WALLACE H. CAMP, OF WATERBURY, CONNECTICUT, ASSIGNOR TO THE SCOVILLMANUFACTURING COMPANY, OF SAME PLACE.

POST-OFFICE BOX.

SPECIFICATION forming part of Letters Patent No. 231,995, datedSeptember '7, 1880.

Application filed August 5, 1880.

To all 'whom it may concern:

Be it known that I, WALLACE H. CAMP, of' Waterbury, in the county of NewHaven and State of Connecticut, have invented a new Improvement inPost-Oftice Boxes; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to bc a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, a front view; Fig. 2, a transverse section between two boxes.

This invention relates to an improvement in the post-office box torwhich Letters Patent were granted to P. H. Camp and myself September 4,1877, No. 194,890. In that patent the metal fra me of eachindependentbox comes in close contact with the frame of adjacentboxes.

It is found very difticult to so construct the boxes that there shall bea close fit between the frame ot' one box and the fra-me ot adjacentboxes, as many times a joint is left, which detracts materially from theappearance of the front.

The object of this invention is to overcome this difficulty; and itconsists in the construe` tion, as hereinafter described, andparticularly recited in the claims.

A represents the side or wall of one box, and B the side of the adjacentbox. a is the metal frame, which covers the outer edge of the box.Adjacent boxes are secured together by forming corresponding grooves bineach box and introducing a tongue therein. In our previous patent thistongue was in thickness only equal to the combined grooves.

(N o model.)

In the present invention I make the tongue d alittle thicker than thedepth ot' the two grooves and extend one toward the front, as at c, theother toward the rear, as at f, and so as to form a partition, as itwere, between adjacent boxes and show at the front and rear. By makingthe one at the front so as not to extend Hush with the frames a space,IL, appears between the two frames, as seen in Fig. 2, and the edges ot'the frames, rounded in shape ot' a bead, give to the front a neat andfinished appearance, and hide to a great extent the heretofore openjoint between boxes. This tongue d c is made ot' wood or other nonmetallic material which will present a strong contrast with the metal,and the part c is preferably made in the same piece with the tongue d;but they may be made separate, the object heilig to show a strip betweenadjacent boxes.

I claim- 1. The herein-described improvement iu independent post-officeboxes, each provided with a metal frame at its front end, consisting ina tongue, c, between the metal frames ot' adjacent boxes, substantiallyas described.

2. In independent post-office boxes, the cor responding grooves b inadjacent boxes, combined with the T-shapcd tongue d c, serving to securethe boxes in position and form a partition between the metal fra-mes ofadjacent boxes, substantially as described.
